  • the blowing pressure detected by the blowing pressure sensor is lower than the ON threshold value set in advance, the sound volume of the noise sound is linearly controlled in accordance with the blowing pressure.
  • a more approximate sound emission characteristic and a more approximate musical performance effect can be replicated with respect to transition from when an exhalation sound is emitted in a musical performance using an acoustic wind instrument to when a musical sound is emitted and transition from when an instrument sound is being emitted to when the musical sound is stopped and only the exhalation sound is emitted, whereby an electric musical instrument can be actualized which provides a musical performance feeling close to that of an actual acoustic wind instrument.

  • the present invention is not limited thereto.
  • a method may be adopted in which waveform data that serves as a noise sound component base is stored in the noise sound source and, by the frequency band of the waveform data being restricted by a band pass filter having a frequency characteristic in accordance with a specified sound pitch, a noise sound in accordance with the sound pitch is generated.

  • a blowing pressure range equal to and higher than the ON threshold value THon in which a pitch sound corresponding to a musical sound is emitted has a conversion characteristic where convergence to a sound volume setting value (upper limit value) close to the ON threshold value THon is performed.
  • the sound volume setting conversion table shown in FIG. 10B has a conversion characteristic having approximate linearity from the start of the blowing of breath to a point close to the ON threshold value THon as in the case of FIG. 10A , and a conversion characteristic by which, in a blowing pressure range equal to or higher than the ON threshold value THon, the sound volume setting value is decreased or converges to a sound volume setting value (lower limit value) lower than a point close to the ON threshold value THon.
  • the sound volume of a noise sound is kept low after a pitch sound is emitted, so that the pitch sound (musical sound) is relatively more highlighted.
  • musical instrument sounds from an acoustic wind instrument are recognized by the human auditory sense such that noise sounds become relatively smaller as pitch sounds become bigger. Therefore, by the sound volume setting conversion table shown in FIG. 10B being adopted, a sound emission characteristic and a musical performance effect close to those of acoustic wind instruments can be replicated.
  • the sound volume setting conversion tables shown in FIG. 10A and FIG. 10B are created on the basis of a curve characteristic approximate to the tendency of the relative sound volume change of a noise sound component when, for example, an acoustic wind instrument is actually played.

  • the sound volume setting value has linearity or non-linearity (curve characteristic) with respect to change in a blowing pressure, and changes continuously.
  • a change characteristic may be adopted by which the sound volume setting value changes in stages with respect to a blowing pressure. In that case, for example, when the blowing pressure is less than the ON threshold value, a relatively low fixed sound volume allowing a noise sound to be emitted is set. When the blowing pressure is equal to or higher than the ON threshold value, a relatively large sound volume in accordance with the blowing pressure is set.
